Mineral Fibre External Wall Insulation Systems

PermaRock Mineral Fibre external wall insulation (EWI) systems are high-performance thermal insulation systems suited for application onto all building types, especially multi-storey buildings where the highest levels of fire resistance and non-combustibility are required.

Incorporating non-combustible mineral fibre (stonewool) insulation (Euroclass A1 – BS EN 13501-1:2007 + A1:2009), systems with an A2-s1,d0 classification in accordance with BS EN 13501- 1:2007 +A1:2009 are tested and accredited for use on high rise buildings, including those with floor levels above 11 metres above ground level.

PermaRock Mineral Fibre systems with PermaRock Silicone^Ultra K 1.5mm, Mineral K 2.0mm, Brick Slip , Brick Effect Render and Dry Dash Finishes are class A2-s1,d0 to BS EN 13501-1:2007 + A1:2009*.

Approvals	BRE Global Certification: BRE Certificate No. 158/12
Thermal Performance	Systems can be designed to achieve U-values which satisfy or exceed current UK Building Regulation requirements.
Weather Resistance	Provides a weather resistant cladding to new and existing backing walls of brick and block masonry, dense and no-fines concrete and sheathed light gauge steel frame and timber frame constructions. Can be designed buildings in locations where the wind driven rain exposure classification is very severe.
Wind Loads	Using a combination of adhesive bonding and mechanical fixing, these systems can be designed to withstand all anticipated wind load (suction) scenarios in the UK.
Impact Resistance	Systems can achieve levels of hard body impact resistance in excess of 40J and can be designed for the zones associated with Categories I, II and III as defined in ETAG004
Fire Performance	Class A1 insulation (BS EN 13501-1:2007 + A1:2009). PermaRock Mineral Fibre systems with PermaRock SiliconeUltra K 1.5mm Finish, PermaRock Mineral K 2.0mm, PermaRock Brick Slips, PermaRock Brick Effect Render and PermaRock Dry Dash are assessed to EN 13501-1:2007 + A1:2009 and are classed A2-s1,d0 (50mm - 250mm). Class O surfaces as defined in the Building Regulations when tested to BS 476 parts 6 and 7 can be achieved. Fire tested in accordance with BS 8414-1: 2002 - compliant with BR 135 Annex A; 2003 (Acrylic Finish).
Water Vapour Permeability	The systems are water vapour permeable. The rate of permeability depends on the system (thickness and decorative finish type) selected
Design Life	Systems can be considered to have a design working like of at least 30 years. Lifetimes significantly in excess of 30 years can be achieved with proper maintenance and repair if damaged
